Ornithosuchidae is an extinct family of pseudosuchian archosaurs (distant relatives of modern crocodilians) from the Triassic period. Ornithosuchids were quadrupedal and facultatively bipedal (e.g. like chimpanzees), meaning that they had the ability to walk on two legs for short periods of time.
Ornithosuchus and Hyperodapedon. Despite this relationship to crocodiles, Ornithosuchus was able to walk on its hind legs, like many dinosaurs. It probably spent most of its time on all fours, though, only moving bipedally when it needed to run rapidly.
Older definitions of the group Archosauria rely on shared morphological characteristics, such as an antorbital fenestra in the skull, serrated teeth, and an upright stance. Some extinct reptiles, such as proterosuchids and euparkeriids , also possessed these features yet originated prior to the split between the crocodilian and bird lineages.
The name Pseudosuchia was originally given to a group of superficially crocodile-like prehistoric reptiles from the Triassic period, but fell out of use in the late 20th century, especially after the name Crurotarsi was established in 1990 to label the clade (evolutionary grouping) of archosaurs encompassing most reptiles previously identified as pseudosuchians.

Venaticosuchus is a genus of pseudosuchian archosaurs from the family Ornithosuchidae.Known from a single species, Venaticosuchus rusconii, this genus is described based on an incomplete skull and jaw (as well as a lost partial forelimb and osteoderms) collected from the Late Triassic Ischigualasto Formation in the Ischigualasto-Villa Unión Basin in northwestern Argentina, which was deposited ...
The largest living species of bear and the largest land carnivore, the polar bear is closely related to the brown bear. So much so, in fact, the two species can interbreed. They live in the Arctic ...
Ornithosuchids were once considered bird-line archosaurs (as implied by their name, which means "bird crocodiles" in Greek), but were later recognized as crocodile-line archosaurs. This reclassification may have inspired Sereno's Crurotarsi, a node-based clade defined by the inclusion of ornithosuchids and other early archosaurs.
